Parameterized Models for Distributed Java Objects

Distributed Java applications use remote method invocation as a communication means between distributed objects. The ProActive library provides high level primitives and strong semantic guarantees for programming Java applications with distributed, mobile, secured components. We present a method for building finite, parameterized models capturing the behavioural semantics of ProActive objects. Our models are symbolic networks of labelled transition systems, whose labels represent (abstractions of) remote method calls. In contrast to the usual finite models, they encode naturally and finitely a large class of distributed object-oriented applications. Their finite instantiations can be used in classical model-checkers and equivalence-checkers for checking temporal logic properties in a compositional manner. We are building a software tool set for the analysis of ProActive applications using these methods.
